Currently, building on any platform that hasn't got getrusage()
requires manual editing of src/backend/port/getrusage.c, becauseits substitute version of getrusage is #if'd out.There is no good reason for that, because configure won't eveninclude the file into the Makefile unless the platform hasn't gotgetrusage. Furthermore, we only have one working substitute versionof getrusage --- the alleged HPUX syscall-based code doesn't work.(It causes a coredump because the syscall returns a struct rusagethat's much larger than the stub struct defined insrc/include/rusagestub.h.) The times()-based emulation works fineon HPUX, however.I propose, therefore, that getrusage.c should just unconditionallycompile the times-based version, and rely on configure to includethe file only if needed. This will be one less manual configurationstep on all platforms that need this code.Patch attached.Tom Lane.
